[ROS tutorial] RTAB-Map in ROS 101

RTAB-Map (Real-Time Appearance-Based Mapping) is a RGB-D SLAM approach based on a loop closure detector.
The loop closure detector uses a bag-of-words approach in order to determinate if a new image detected by an RGB-D sensor it is from a new location or from a location that it has been already visited.
Of course, this is a very summarized explanation, you will get more details on how this loop closure detector works inside this Course.

In this course you will learn how to perform RGB-D SLAM by using the rtabmap_ros package.

At the end of the course, the following topics will have been addressed:
- Basics of RTAB-Map
- How to use the rtabmap_ros package
- How does loop closure detection work internally
- How to generate a 3D Map of an environment
- How to perform Autonomous Navigation
